Havingj given a general. description. of" m m vention I. will now; in orderto' make the same" moreiclea'r, refer to the accompanying twosh'eets of drawings inwhichlikekchai'acters refer tdlik'e:

carriage provided with rollers 2 journaled in bearings mounted on the girders 3 and adapted to travel on the rails 4.

The axle 5 of two of the rollers 2 have gears 6 mounted thereon meshing with pinions l on the ends of a driveshaft 8, having a gear 9 mount- -ed centrallythereon. for 'meshing with a pinion I 0 on the shaft of a motor I I for rotating the shaft for operatingthe carriage.

Secured on top of the carriage near the rear end at one side thereof is a center bearing plate l2 having a central perforation adapted to receive the king bolt 13 extending from a bearing plate 14 secured to the under side of the pivoted platform [5 near the inner end, the forward and intermediate portion of the platform being supported on track segments lBand I! by means of rollers I8 which are secured to the platform by means of brackets, the forward end of the pivoted platform being limited in its lateral movement by means of stops l9. Standards 20, 2|, and 22 are mounted at spaced intervals on the platform in which are mounted idler rollers 23 for guiding a pusher ram 24 which has a rack formed on its under side for meshing with a pinion 25 on shaft 26 journaled in the bearing 22, the outer end of said shaft being connected by means of reduction gearing 2'1, driven by means of a motor 28. Mounted in the platform l5 laterally thereof at one side of the pusher ram 24, is a door manipulator 29, mounted in standards 30 and 3| between idler rollers 32 for guiding the same. The under side of the shaft of said door manipulator having a rack formed thereon as at 33 meshing with a pinion 34, the shaft of which is journaled in standard 3| and connected with reductiongearing 35 and actuated by means of a motor 36. The forward end of the door manipulator being formed with hooks 3'! for engagingthe lugs 38 on doors 39 for closing the pusher sideof the coke ovens 40. In order to ad- I just or swing the outer end of the platform [5 with the pusher ram 24 and the door manipulator 29 mounted therein, a motor 4! is mounted on the front end of the platform which is connected by means of gearing 42 to a rack 43 formed on the track segment H.

A leveling bar 44 is mounted laterally of the pivoted platform on one side of the carriage l, the forward end of the leveling bar being supported between standards 45 and idler rollers 48 while the rear end of the leveling bar is guided between posts 41 and idler rollers 48, mounted on a car 49 supported on wheels 50 engaging a track 5|, said car having a motor 52 and reductiongearing 53 for'bodily advancing the car and the leveling bar. The motor 52 and gearing 53 connected therewith will advance the leveling bar slowly into the coke oven. When the leveling bar encounters a pile of coal whichcannot be leveled bythe slow movement of the leveling bar into the oven the leveling bar can be given a short stroke reciprocating motion independent of the motor 52 by throwing in the motor 54 geared to crank arms 55 and pitmen 56 pivoted to a sector gear 51 journaled on the car body. This sector gear 51 engaging gears 58 and has a gear 59 adapted to engage a rack 60 on the under side of the leveling bar.

A mud'buggy or bucket BI is pivoted by means of i an arm 62 to a standard 63 which may be swung outwhen desired for sealing the doors after they have been replaced before charging the ovens. An operators cab 64 is mounted on the'carriage in which the controllers (not shown) for operating the different motors may be in stalled.

The operation of my invention is as follows: After the door of the first oven is removed by means of the door manipulator 29 and the platform l5 swung from the dotted position into the full line position indicated in Fig. 1 of the drawings the pusher ram 24 is then advanced into the oven the full length thereby ejecting the coke from the oven into a coke quenching car or the like receptacle on the opposite side of the battery, the pusher ram 24 is then returned to the position'shown in the drawings and the platform swung into the dotted line position and the door replaced in the end of the oven, the carriage will then be advanced a distance equal to five ovens until the leveling bar is properly centered for its operation, the luter man will then swing out his luter box, and start his operation of sealing the door, while he is swinging out his luter box and completing his operation the movable platform [5 holding the pusher ram 24 and door manipulator 29 will swing into position, remove the door of the oven and swing the pusher ram into operating position. The operation of mudding the previous door taken off, taking off the door of the next oven to be pushed and swinging the pusher ram into position for its work will be finished at the same time. The first oven discharged having been recharged with coal in the usual manner the control is then thrown in, starting the leveling bar into operation, this can be then left to itself while the operator pushes the coke from the oven, after the coke in the oven has been ejected and the pusher ram retracted into its normal position, the door manipulating machine is operated to replace the oven door, the leveling operation has been completed and the carriage with the machines mounted thereon moves up another series of five ovens to repeat the cycle.
